Description
Technical field
The utility model relates to medical instruments field more particularly to a kind of rib cage intramedullary nails.
Background technique
Traditional fracture of rib treatment method is to give analgesic to the patient of fracture of rib, or with fixing belt outside chest
It is fixed, although alleviating pain, respiratory state is made to be deteriorated；Secondly, the rib cage board fixer occurred later, to a certain degree
On alleviate the pain of sufferer, and do not interfere the respiratory state of sufferer, but wound area is larger, needing to do open chest surgery can
It is installed.
Utility model content
In view of the drawbacks described above of the prior art, the purpose of the utility model is to provide a kind of easy to operate, safe and reliable
Rib cage intramedullary nail.
The purpose of this utility model is achieved through the following technical solutions:
A kind of rib cage intramedullary nail, including guide part and fixed part；The material of rib cage intramedullary nail has certain elasticity；Institute
Guide part is stated to be disposed on the same plane with the fixed part；One end of the guide part is connected with tapering, the tapering
End is in arc-shaped；The position that the guide part is connect with the tapering is taper, and identical as the taper in the tapering；It is described
The other end of guide part is connected with the interconnecting piece；The fixed part is connected with the guide part by the interconnecting piece；
The interconnecting piece is parabola or arc shape；The two sides of the fixed part are provided with holding claw；The holding claw and the fixed part
It is substantially perpendicular；Locking hole is provided on the fixed part.
Further, the locking hole is two；The holding claw is arranged on the fixed part far from the interconnecting piece
Adjacent one end, one of locking hole are arranged among two holding claws, another locking hole is positioned close to the interconnecting piece
Side.
Further, the material of rib cage intramedullary nail is pure titanium.
Compared with the existing technology, the characteristics of the utility model and progressive as follows:
1, the end of the rib cage intramedullary nail of the utility model is in arc-shaped, and no wedge angle has guiding role, convenient in rib cage
Interior movement；The position that guide part is connect with tapering is taper, and identical as the taper in tapering, and such guide effect is more preferable, more just
In being moved in rib cage.
2, the guide part of the rib cage intramedullary nail of the utility model and fixed part are disposed on the same plane, and processing is facilitated to make
It makes, simultaneously because rib cage intramedullary nail has elasticity, the fixation of rib cage intramedullary nail will not be influenced.
3, the interconnecting piece of the rib cage intramedullary nail of the utility model is parabola or arc shape, reduces stress and concentrates, works as rib
When intramedullary pin enters operation path and deforms, guarantee that rib cage intramedullary nail will not be broken.
4, the adjacent one end on fixed part far from interconnecting piece is arranged in the holding claw of the rib cage intramedullary nail of the utility model, wherein
One locking hole is arranged among two holding claws, another locking hole is positioned close to the side of interconnecting piece, is inserted by locking nail
Enter locking hole to be further fixed, the reliability of rib cage Intramedullary nailing can be greatly reinforced in this way.
5, compared to common rib plate, the rib cage intramedullary nail of the utility model is inserted into pulp cavity, has wound small, operation letter
Single, patient restores fast, good operation effect；It is substantially reduced sufferer pain intensity, increases lung capacity, reduces the hair of lung's complications
It is raw, shorten average stay.
6, the utility model is pure titanium rib cage intramedullary nail, and histocompatbility is good, substantially without artifact under X-ray, so can be not necessarily to
It takes out.
7, the geometric center of sclerite is fixed in bone surgery, and the rib cage intramedullary nail of the utility model can fix fracture in solution
Cut open position；Compared to the fixation with bone plate, it is advantageous that more meeting the stress line of force of human body.
Detailed description of the invention
Fig. 1: the perspective view of rib cage intramedullary nail；
Fig. 2: rib cage intramedullary nail acts on fission frame section surface schematic diagram；
Fig. 3: rib cage intramedullary nail holding claw compresses fission frame section surface schematic diagram.
Specific embodiment
The utility model is further described with reference to the accompanying drawings and examples.
As shown in Figure 1, a kind of rib cage intramedullary nail, including guide part 2 and fixed part 4；The material of rib cage intramedullary nail has
Certain elasticity can be deformed voluntarily as needed；Guide part 2 is disposed on the same plane with fixed part 4, facilitates processing and manufacturing,
Simultaneously because rib cage intramedullary nail has elasticity, the fixation of rib cage intramedullary nail will not be influenced；One end of guide part 2 and 1 phase of tapering
Connection, the end in tapering 1 are in arc-shaped, and no wedge angle has guiding role, convenient for moving in rib cage；Guide part 2 and tapering 1
The position of connection is taper, and identical as the taper in tapering 1, and such guide effect is more preferable, is more convenient for moving in rib cage；Guiding
The other end in portion 2 is connected with interconnecting piece 3；Fixed part 4 is connected with guide part 2 by interconnecting piece 3；Interconnecting piece 3 is parabola
Or arc shape, reduce stress and concentrate, when rib cage intramedullary nail, which enters operation path, to deform, guarantees that rib cage intramedullary nail will not
It is broken；The two sides of fixed part 4 are provided with holding claw 6, can preferably be fixed on dislocation fracture rib cage；Holding claw 6 and solid
It is substantially perpendicular to determine portion 4；Locking hole 5 is provided on fixed part 4, locking hole 5 is two；The setting of holding claw 6 is separate on fixed part 4
The adjacent one end of interconnecting piece 3, one of locking hole 5 are arranged among two holding claws 6, another locking hole 5 is positioned close to
The side of interconnecting piece 3 is inserted into locking hole 5 by locking nail and is further fixed, can greatly reinforce rib cage intramedullary nail in this way
Fixed reliability.
Locking hole 5 is mainly used for when encountering special ribbed shape, when holding claw can not be leaned on to hold fracture rib cage tightly merely, can make
It is locked with locking nail, so that preferably rib cage intramedullary nail is lock on fracture rib cage.
Further, the material of rib cage intramedullary nail is pure titanium.
As Figure 2-3, rib cage is misplaced；Fracture is operated using rib cage intramedullary nail；Operation side
Method is as follows: (1) appropriate location at fracture of rib, and entrance is selected to establish operation path by supporting tool；(2) such as Fig. 2
It is shown, after operation path is established, fission 7 surface texture of rib cage is removed, according to actual needs in the rib cage marrow of selection respective model
Nail is hit exactly according to fracture site frame bending degree with fracture is stuck in after hand pre-bending；(3) as shown in figure 3, with large size or trumpet
Clip Applier carries out a point pawl and applies, and clamp aft rib intramedullary pin is only needed to loosen not on rib cage；(4) under special circumstances, if
It does not lock yet, locking nail may be used and be fixed.
But those of ordinary skill in the art it should be appreciated that more than embodiment be intended merely to illustrate this
Utility model, and being not used as the restriction to the utility model, if in the spirit of the utility model, to
Variation, the modification of the upper embodiment will all be fallen in the Claims scope of the utility model.
